the brakes on a 32 are 345mm with twin piston calipers , they should bolt straight on as the hubs for 4wd 312mm are the same for the R32s , it will be heavy , the pads and discs are uber expensive YOU WILL need 18s ,
and ifyou jump on them id say the car will flip, i can see your viewpoint max , but 312s on standard wheels- even 16s are grand ,
